About this test
This independent HPLC-UV/VIS lab test confirms KLOW 50mg/10mg/10mg/10mg from Certified Peptides at >99.00% purity. The assay measured 49.74 mg of GHK-Cu, 9.94 mg of TB-500, 12.00 mg of BPC-157, and 11.22 mg of KPV per vial. The analysis was performed by Vanguard Laboratory and reported on January 6, 2026, under Batch Number 250929KL503.
KLOW is a proprietary four-peptide blend combining GHK-Cu (a copper peptide researched for skin remodeling and collagen synthesis), TB-500 (Thymosin Beta-4, researched for tissue repair and anti-inflammatory effects), BPC-157 (a pentadecapeptide researched for wound healing and gastrointestinal protection), and KPV (an anti-inflammatory tripeptide derived from alpha-MSH). Additional testing confirmed endotoxin levels below 0.05 EU/mg (LAL method), sterility with no growth detected (USP <71>), and non-detectable levels of heavy metals including chromium, arsenic, cadmium, lead, and mercury via ICP-MS.
